In addition, with the objective of preserving adequate liquidity in the secondary market following the Admission, the Offering will be structured to ensure a diversified shareholder base, whereby no individual new investor is expected to hold more than a 3% stake in the Company upon completion of the Offering. This approach is intended to support healthy trading dynamics and enhance free float over time

Orders placed by cornerstone investors will be based on the prospectus approved by and registered with the CNMV,

The Offering is expected to consist of a primary offering of newly issued shares by the Company, targeting an equity raise of approximately €150 millions (excluding any over-allotment option). The Offering will be made to qualified investors in the European Economic Area and in the United Kingdom. The Shares will not be offered or sold in the United States.

Further details of the proposed Offering will be included in the prospectus to be approved by, and registered with, the CNMV in connection with the Offering and the admission to trading on the Spanish Stock Exchanges, which will supersede this announcement in its entirety.

The prospectus approval process is ongoing and will include full details on the Offering and its expected timetable. Once approved, the prospectus will be published and made available on the Company’s website and on the CNMV’s website (www.cnmv.es).

Any acquisition of shares in the Company should be made solely on the basis of the prospectus approved by, and registered with, the CNMV. The approval of the prospectus by the CNMV does not constitute an evaluation of the merits of the Offering.
